Expiration & Storage Tips
When does coriander seed expire?
Coriander seeds, if stored properly, have a rather long shelf life. When unopened, they can last up to two to three years past the printed date on the package. If stored properly, once opened, they can still last anywhere from 1 to 2 years. However, they may lose their potency over time, so for best flavor, try to use within a year. As for freezing, it isn't common for households to freeze coriander seeds, and freezing doesn't extend its shelf life as it does for some other products.
How do you tell if coriander seed is bad?
The best way to tell if your coriander seeds have spoiled is by their smell and appearance. Fresh coriander seeds should have a strong spicy aroma, so if they smell musty, moldy or have no smell at all, they likely have gone bad. Look for any signs of decay, discoloration or mold. But the most common way they spoil is simply by losing their potency and flavor over time, so if they taste weak or off, it might be time for a new batch.
Tips for storing coriander seed to extend shelf life
• Store your coriander seeds in an airtight glass jar, vacuums seal bag or a resealable plastic bag. Air, moisture, and light can cause the seeds to lose their flavor over time, so keeping them sealed will help prolong their life.
• Keep them in a cool, dry and dark place like a cabinet or pantry. Heat, moisture, and light will hasten the deterioration of the seeds' quality.
• If you have ground the seeds, use the powder as soon as possible. Ground coriander loses its flavor more quickly than whole seeds.
